ative relationship. Numeral 18 designates a V pinion secured to the shaft 19, which inturn is rotatively secured .to the frame 6. The pinion 18 is in mesh with the chain 17 and acts as a tightening means for the chain 17 By the structure thus far described, when the drive shaft 10 is rotated the sprocket wheel willbe rotated. On aybracket 'secured to the frame6 are positioned hangers21. In

the hangers 21 is rotatively positioned the shaft 22. On the shaft 22 are-secured the throw in hooks 23. These hooks are norinally in the position shown by the full line in Fig, )2, and projectin the vat 9 so that. whenin the vat 9, the horizontal portion of the hooks will be ofsuc'h depth in the vat-that they will pass under the hog, that is to be thrown vinto..thefn achine when the hog is moved in the vaton the hook23. In order to rotatethethrow in ihook 23 from the position shown-in solid l-inetothat shownin dash linethat is from.theposition" which the hog 7 assumes in the vation the hook to the position the hook assumes in throwing the hog into the machine, the shaft-22 must be oscillated. Th mechanism for producingthis oscillation is the following r 7 g Numeral 24 designates a link secured to the it must (be necessary to' selectively operate shaft 22.; Numeral-1 25vdesignatesna link securedfto the shaft 16. Numeral 26 designates a rod, .which is rotatively secured at one end to the end of the link'25 and rotatively'secured at its otherendto-the link 24. It

. will be seen, therefore, that when the sprocket wvheel l5is rotated in the. direction of the arrowshown i-n Fig.2that the rod 26, the links 24 and'25 will assume the position shown in dash line in Fig. 2 and that this position brings the throw inhooks 23 to, the position shown in Fig. 2, that is to the throw in position. Obviously after the throw in hooks 23 have beenbroughtto' the position shownin' thevldash l ne v1n; Fig.2and the hog-has been thrown into the machine, the-throw inhooks 3 23 mustbe returned to their normal position in the zvat, 9;. Eurthermorefltis obvious that the throw in hooks 23 and that thisjoperation ust ice-independent: of -the continued r-ota .tionbfth shaft 16.

sition; The hog enters the machine proper in the direction 50f the long "arrow "shownin Fig. 1 2; }Ni1mera1 30' designates a series, j 0f hooks, which are secured at intervals to the shaft 31, which is journaled tothe frame 6. Between the hooks 30 are rigidly secured a series of grate bars 32. When the hooks 30 are in their normal position they are in the same plane withthe grate bars 32 and together form thesupport for the hog in the machine, While the hogis ,in this position the scrapingis accomplished. On thedrive shaft 10 at intervals between the hooks 30 and the grate bars 32 are keyed the webs 33,

having the pointed projections 34 to the end of which are secured the web belting paddles 35 nearthe ends ofjwhich are secured the scraper-hooks 36. [When the scraper hooks 36 are rotated in the direction of the arrow inFig. 5, they meetvthe bristles of the hog in the position shown in Fig. 5; and produce a scraping action on the 'bristlesiof the hog rotating the hog, but at a much lesser rota-- tionthan that of thescraper hooks 36 and when the: hog. is positioned on'oneside as shownin Fig. 5, the scraper hooks 36 scrape against the grain of the hogbristles. -As the hog is'rotated, when the other side ofthe hog comes in contact with the scraper hooks 36',

of the grain of the bristles and the dehairing will then be imperfect, as previously 1nd1- catedi Furthermore, unless an upper support isapplied over. thehog, the hog will the hooks will be scraping in the direction in its rotation be-moved or bumped up and down ver-tically' in and out of engagement with the scrapers and the dehairmg will be imperfect. My auxiliary; scrapers act as a support for the hog, preventing this vertical bumping mot-ion as well asjpresenting scrapers in contact with the hog bristles against the grain of the bristles. The constructlon of the auxiliary scrapers and support'is the fol lowlng Numeral. 37 designates a bracketjsec ured :to the frame 6, on which isjournaled the shaft 38., Toqthe shaft 38iskeyed the link 39. Numeral 40 designates a rod rotatively n secured at one end to thefree end-pf the link '39. On therod 26 is secured the plate 41 .forming,together with a portion of therod 26, a slot, into which the end of the rod .40

passes; Thefdisengagement of the rod 40 from this slotisprevented bye-the nut 42.

It will be seen that it is necessary to oscillatethe paddles-43-out of the'path of the hogin its entry lIltOf-tl16j1T1aCl'llIl6, 7

otherwise: the paddles 43 wouldbe bent or,

broken or, would lie beneath the hog and be inoperative. Therefore, when the hog is r W'hen the rodilO is pushed to the right in Fig.2, the'paddles 43will be brought to their "operative positions. When the rod 40 accomplished'by the movement of the shaft is pulled to the left in Fig. 2, the paddles 43 will be brought to the. dash line position shownin Fig. 2. The movement of the rod 40 to the right or left: isaccomplished by "the movement'of the rodeo. It will be seen that the free end of the rod 40 may movein ,the slotbetween the plate 41 and the rod 26; I Then the rod 26 is moved from the position :shown in'solid lines in Fig. 2 to that shown by dash'lines in the same figure, it will be seen that the rod 40 will moveto the right or V 2o left depending on the direction of the movement of the rod 26. It willbe' remembered that-the-rod'2og-i's the rod thatjactuates the throw in hooks 23. After the hog hasbeen placed in operative 'positionfor ideha-ir'ing, the'paddles 43 must be brought to their operative positions. The paddles 4:3 must'be in the position shown in dashfline in when the throw in hooks 23 are in the position shown vby dash lines'in the samefigure and must remain in that position, until the hog is placed in operative position for dehairing. The throwin hooks 23 must then be placed in the position shown in solid lines in Fig. 2, ready to receive the next hog,- and V the paddles .43 must be brought to their op,-'

: erative position, that is the positionshown by the solid lines in Fig. 2. These two operations are performed by 'operatlng the clutch 27; Whenfthe throw inhooks are moving to the dash lineposition in Fig. 2,

the rod 40 is pulled 'to the left and this pull 5 continues until the throw'in hooks 23 reach their upper limiting position; Upto this point the power is being applied to the throw in hooks 23, thereby lifting the hog out of s thevat 9,. After the hog is thrown from the i hooks'23, the power is disconnected from the I link-4.6 and y ecured at itsother nd to the free'en'd of the link47. I Numeral 4c9, designates a clutch mechanismsimila'r to a the clutch mechanism 27 secured to the shaft Numeral rdesignates a lever connected to the clutch mechanism 49. Numeral 51designatesa rope connected to the lever 50. By 7 means of the rope 51, the. link. 46 may selectively be made to oscillate, which oscillation through the instrumentality of the link 47' and the shaft 31, oscillates the throwout hooks 31. By this operation, the hog is moved from the position it had when the throw out books 30 'were in the position shown by the solid lines in Fig. 3 to the position they assume when in the dashlineposition in the same] figure. From the last posi- I tion,the hog is expelled from the machine 7 gravitationallyl The hooks 30 return to their solid line position in Fig.2 gravitationally. Every alternate paddle 43 is formed I without scrapers and bent inthe opposite direction of the scraper ends of the remaining paddles inorder to prevent a lodging ofa" hogs-foot between adjacent paddles.
